結論（おすすめ1つ） 迷ったら Render に乗り換えるのが無難です。理由は3つ。Heroku に最も操作感が近く（git push デプロイ・buildpack 互換）学習コストが小さいこと、Web/DB/cron/Worker を1サービスで完結でき構成が散らからないこと、render.yaml でインフラをコード管理できて再現性が高いことです。スピード重視で小さく始めるなら Railway、Docker前提で低レイテンシな常時稼働が要るなら Fly.io を検討します。 比較表（料金/無料枠/移行コスト/対応言語） 項目 Render Railway Fly.io 料金 従量＋固定プラン（公式の料金ページで要確認） 従量課金中心（公式の料金ページで要確認） リソース従量（公式の料金ページで要確認） 無料枠 有無・条件は公式の料金ページで要確認 クレジット制（公式の料金ページで要確認） 有無・条件は公式の料金ページで要確認 移行コスト 低（Heroku同等のgit push/buildpack互換） 低（GitHub連携で自動検出） Continue reading 【2026】Heroku 代替 2026 (Render/Railway/Fly.io)：料金・移行コストで選ぶ→

結論（おすすめ1つ） 静的サイト・JAMstack 中心で帯域コストを抑えたいなら Cloudflare Pages への移行を勧める。理由は3つ。Cloudflare はビルド成果物の配信帯域に課金しない設計で大量アクセス時のコスト見通しが立てやすいこと、Workers と統合してエッジ実行を同一プラットフォームで完結できること、独自ドメイン配下の DNS・CDN・WAF を一元管理できることだ。逆に Next.js の ISR や Image Optimization、Server Actions を全面的に使い込んでいるなら Vercel 残留が無難で、無理な移行はコスト増になる。 比較表（料金/無料枠/移行コスト/対応言語） 項目 Vercel Cloudflare Pages 料金体系 帯域・実行回数・ビルド時間に従量課金（公式の料金ページで要確認） 静的配信は帯域無課金、Functions 実行はリクエスト課金（公式の料金ページで要確認） 無料枠 Continue reading 【2026】Vercel vs Cloudflare Pages 移行ガイド：料金・移行コストで選ぶ→
